I would like some consistency. Either all comparisons between objects
of different types throw an exception by default or none does.

Did you see examples that show why Guido wants things to behave whatever
way he wants? I didn't and I didn't see examples from you either.

Guido's idea is a change from current behaviour. Each time I saw some
argue a change here, people seem to expect a use case from that person.
So why ask a use case of me and just accepy Guido's idea.
